Evaluation of Tumor Response Using Alpha-fetoprotein and Des-gamma-carboxy Prothrombin in Hepatocellular Carcinoma Patients Who Underwent Transarterial Chemoembolization.

Introduction: The aim of the study is to evaluate the role of alpha-fetoprotein (AFP) and des-y-carboxy prothrombin (DCP) in the assessment of treatment response at one month in patients with hepatocellular carcinoma (HCC) treated with trans-arterial chemoembolization (TACE). Methods: From March 2016 to April 2017 a number of 59 patients diagnosed with HCC were prospectively enrolled. A TACE procedure as initial treatment modality was performed in 41 patients. AFP and DCP serum levels were measured and clinical features were determined for all the patients that were included. The Wilcoxon rank test was used to compare variables at baseline and at one month after the procedure. Results: Treatment was performed in 86.4% of the patients diagnosed with HCC, 27 patients received a classical TACE procedure, 14 patients were treated with DEB-TACE, radiofrequency ablation was performed in 3 patients and 4 patients received a liver transplant as initial treatment. Systemic therapy with Sorafenib was started in 3 patients (5%) and in 8 cases no treatment was performed. AFP value significantly decreased at one month in patients that underwent TACE therapy (median value 240.3 vs. 123.7 ng/mL, p=0.020). The same significant decrease was noted for DCP values (median value 1376.8 vs. 769 mAU/mL, p=0.0033). Both AFP (85.5 vs. 18.7 ng/mL, p=0.035) and DCP values (693.2 vs. 58.2 ng/mL, p=0.0003) were significantly lower only in subjects who achieved complete response after TACE and not in patients with partial response. In patients treated with TACE therapy, there was a down-sizing of the maximum diameter of the tumor nodule (30 vs. 27 mm, p=0.02). There was a significant decrease of AFP and DCP values after complete response in HCC patients treated with TACE. DCP is a more effective tumor marker in predicting response than AFP, with no benefit found in their combination.

Early Prediction of the Outcome Using Tumor Markers and mRECIST in Unresectable Hepatocellular Carcinoma Patients Who Underwent Transarterial Chemoembolization.

We examined early predictors of the outcome in hepatocellular carcinoma (HCC) patients after transarterial chemoembolization (TACE). We analyzed 116 patients with unresectable HCC treated with initial TACE. α-Fetoprotein (AFP) or des-γ-carboxy prothrombin (DCP) response was assessed in patients who had baseline AFP levels ≥200 ng/ml or DCP ≥60 mAU/ml; a positive response was defined as a reduction of >50% compared to baseline 1 month after TACE. A baseline AFP level ≥200 ng/ml was associated with a poor overall survival (OS) (29.4 vs. 6.1 months; p <0.0001). AFP response had no significantly prognostic effects on the OS. Conversely, although the baseline DCP did not influence the OS, DCP responders showed a significantly better OS than nonresponders (67.0 vs. 19.8 months, p = 0.020). The baseline AFP (p = 0.004) and initial tumor response evaluated by the modified Response Evaluation Criteria in Solid Tumors (mRECIST) (p = 0.012) were found to be independent predictors of the OS. The combination of the baseline AFP and initial assessment by mRECIST allowed stratification of the OS. The combination of the baseline AFP level and mRECIST is useful for the early prediction of the OS in HCC patients who underwent TACE.

Tumor Markers AFP, AFP-L3, and DCP in Hepatocellular Carcinoma Refractory to Transcatheter Arterial Chemoembolization.

We examined tumor marker levels to assess in more detail transcatheter arterial chemoembolization (TACE)-refractory hepatocellular carcinoma (HCC). We enrolled patients treated from 2000 to 2011 for HCC beyond the Milan criteria who had good hepatic reserve function (Child-Pugh A) and no portal vein thrombosis or metastases (n = 154). The modified criteria for being TACE-refractory according to the Liver Cancer Study Group of Japan (m-LCSGJ), from which the tumor marker item was excluded, and the Assessment for Retreatment with TACE (ART) score were used for determining whether the HCC was TACE refractory. α-Fetoprotein ≥ 100 ng/ml, fucosylated α-fetoprotein ≥ 10%, and des-gamma-carboxy prothrombin ≥ 100 mAU/ml were used to define whether tumor markers were positive. We added up the number of positive tumor markers as a prognostic score to assess in more detail the evaluation of TACE-refractory HCC. In order to divide the patients into a refractory and nonrefractory group, the m-LCSGJ criteria [mean survival time (MST) 27.1 vs. 49.9 months; p < 0.001] were superior to the ART score (MST 22.0 vs. 35.1 months; p = 0.051). In the refractory group according to the m-LCSGJ criteria, the patients with a low score of positive tumor markers (<2) after 2 sessions of TACE (n = 36) showed a better prognosis than the others (n = 72) (MST 37.7 vs. 23.2 months; p = 0.014). Patients being nonrefractory according to the m-LCSGJ criteria had a better response, and using the number of tumor markers (≥ 2) is an easy method for predicting the response to TACE and for a more detailed evaluation of TACE-refractory HCC.
